## Related Questions  The rate of energy conversion - not just electrical energy, but any type of energy - is called POWER. The SI unit is the watt, which is equal to joules per second. A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts. Watts means joules per second (joules / second), or equivalently, joules is watts times seconds.A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts.

Watts means joules per second (joules / second), or equivalently, joules is watts times seconds. Work is how much energy is transferred, measured in Joules. Power is how fast or slow the work is transfered, measured in Joules per second. One joule per second is called one Watt of power. This meams a 60 Watt light bulb converts 60 joules of electrical energy into roughly 15 joules of light and 45 Joules of heat every second its switched on for. 1 joule is the energy equal to 1 watt for 1 second.100 joules = 100w for 1 second.A 100 watt light bulb converts 100 joules of electrical energy into heat and light every second.Only about 1% of this is useful light, the rest is wasted as heat.AnswerPower is defined as the rate of doing work. As work is expressed in joules (J), it follows that power is measured in joules per second (J/s) -however, in SI, this is given a special name: the watt (W).So one joule per second is exactly equivalent to one watt. Therefore, 100 J/s is exactly equivalent to 100 W. The rate of conversion of any type of energy is called power. In the international system (SI), the unit for energy is the joule; the unit for power is the watt, which is equal to joules/second. Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules). The rate of energy transfer or transformation is mesured in joules / second, also known as watts.The rate of energy transfer or transformation is mesured in joules / second, also known as watts.The rate of energy transfer or transformation is mesured in joules / second, also known as watts.The rate of energy transfer or transformation is mesured in joules / second, also known as watts. Power (watts) is amperes times voltage, or joules per second. Energy is joules, or watt-seconds. The length of time an electrical load is on is proportional to energy, not power. Power is always the time-rate of energy, i.e. the rate of change (or transfer) of energy with respect to time.If Energy is measured in Joules, then one Joule being transferred in one second is equal to one Watt of power.Electrical power is the time rate of change of electrical energy, P=dE/dt.Power = energy / timeIt usually referst to some type of energy transfer. In SI units:Watts = joules / second The Joule is a unit of energy, while the Watt is a unit of power. Joule is the alternate name for a Newton-meter of energy, and Watt is the alternate name for a Newton-meter per second of power. This means that one Watt is one Joule per second; a 100-Watt light bulb converts 100 Joules of electrical energy every second into heat energy and light energy. That is called "power". The SI unit for power is the watt, which is equal to joules/second. Watts is energy output. Watts is joules per second. Joules is energy. In physics, the total amount of energy is measured in joules. The rate of energy use - joules/second - is the power, the unit is also known as watt. Electricity companies tend to use another measure for energy use: the kilowatt-hour (kWh), which of course is equal to 3.6 million joules. 40 Joules, I think, as the formula for Watts is Joules/Second = Joules per second 40 Watts should equal 40 Joules per one second... Nuclear energy is a quantity of energy measured in Joules, so it has the same units as mechanical or electrical energy. Nuclear power is the rate of production of nuclear energy, so it is Joules per second, or Watts, as other forms of power are.Remember: power = energy flow per second. This applies to all forms of energy. Power is energy per time unit. It is measured in is Joules / second, also called Watts.Power is energy per time unit. It is measured in is Joules / second, also called Watts.Power is energy per time unit. It is measured in is Joules / second, also called Watts.Power is energy per time unit. It is measured in is Joules / second, also called Watts. 3500W, or 3.5kW Power is measured in Watts; one Watt is 1 joule of energy converted/used per second. So, 3500 joules a second is 3500 Watts. Electron flow is current, or coulombs per second. Electron potential is voltage or joules per second.  Every second a 150 Watt bulb converts 150 Joules from electricity into heat and light. The number of Watts tells you how many Joules pass per second. The official unit for any type of energy (not just mechanical energy) is the joule. The official unit for any power (not just electrical power) is the watt, equal to joules / second. Joules (energy) are not equivalent to Watts (power).If something converts 6 Joules every second, it is 6 Watts. If it takes ten seconds to convert 6 Joules, its power is 0.6 Watts.Multiply the Watts by the seconds to find the Joules.CommentYou do not 'consume' power. Power is simply a rate; you cannot consume a rate! You consume energy; the rate at which you consume it is power. Electric power (how fast energy is being converted into or out of electrical energy) is measured in Watts. Electrical energy is measured in Joules. i Watt for 1 second is 1 Joule. 1000 Watts for 3600 seconds is 3.6 Megajoules, also known as a kilowatt-hour or a Unit of electrical energy. This is not a valid question by itself. Joules are units of energy, while Amps are units of electrical current. However, if you also know the Voltage of the electrical current, you can multiply the Current[Amps]*Voltage[Volts] to get the Power in Watts. Watts are equivalent to Joules per second. If you then know the amount of time of the current flow, you can calculate the total number of Joules by multiplying the Power[Watts]*Time[seconds] = Energy[Joules] .
